Is 18 Cooper Street, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 10 open Class C, with nothing filed or new in the last 180 days. That window ends September 26, 2026. It compares certifications filed with new Class C violations, and it describes what happened, not what anyone intends.

When were certifications filed on Class C violations at 18 Cooper Street, Brooklyn?

Since September 28, 2023, a certification was filed on 1 Class C violation, by the original certify-by date. A certification is the filing, dated when it was made, not HPD's acceptance of it. It is compared with the original certify-by date on the notice. A granted postponement moves that date and the city's data keeps only the first, so a certification counted after it may still have met a postponed date.

Has DOB received complaints about 18 Cooper Street, Brooklyn?

Yes. 5 DOB complaints in the last 12 months, 1 of them conversion complaint. The newest was filed July 16, 2026. Anyone can complain to DOB about a building or the work going on in it, and DOB then inspects and decides whether there is a violation. A conversion complaint says an apartment may have been added or changed without approval. It is a complaint, not a finding.

Are any HPD emergency repair orders at 18 Cooper Street, Brooklyn marked completed?

Yes. 2 completed HPD emergency repair orders since September 28, 2023, awarded for $2,584 in total. The most recent of the 2, a general construction order, was opened June 25, 2025. HPD orders an emergency repair when a hazardous condition cited in a violation, or in another agency's emergency order, is not corrected, and does the work itself or through a contractor. The amounts are what the orders were awarded for, not a bill: this page does not show what was charged to the property or whether it was paid. Orders for lab tests, such as dust-wipe and asbestos samples, are not counted.

When was 18 Cooper Street, Brooklyn built?

The city's record gives 1910 as the year 18 Cooper Street, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a three-family dwelling with 3 floors.

How many apartments does 18 Cooper Street, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 3 residential units at 18 Cooper Street, Brooklyn. The count is for the whole tax lot.

Where do these numbers come from?

From New York City's own data: HPD housing violations and OATH/ECB hearing results, read whole rather than sampled. It also draws on DOB complaints, HPD emergency repair orders and the city's PLUTO tax-lot file. This page is current through September 26, 2026. The city's data changes daily, so a violation certified after that can still show as open here; the city's own page for this building is linked above.

Sources. HPD housing violations and OATH/ECB hearing results, plus DOB complaints, HPD emergency repair orders and the city's PLUTO tax-lot file. Counts cover HPD Class B and C violations from the last 3 years that HPD still shows open, and OATH/ECB summonses from the same 3 years that the city still shows active. The city's own pages can show more, never fewer.
